Ultra-Mini DyadTM
UM2
Features * Small size Easily surface mountable * Hermetically sealed * Easily formed leads
Description Clare's Ultra-Mini DyadTM is well suited for small, signal switching applications. The small size lends itself to surface mountable applications; working well on higher density PC boards. The Ultra-Mini DyadTM has sputtered ruthenium contacts and an extraordinary seal strength achieved by a patented laser sealing of the leads. In low level or dry switching environments, switches typically exceed 1 billion operations.
Applications * Proximity Sensors * Relays * Telecommunications * Automation control * Medical
